    Voeding nog sterk genoeg?

    Hey

    Ik heb een corsair VX450 voeding en zou graag crossfire met 5850 doen, zou da gaan of net niet?

    Mijn systeem is:

    AMD Phenom II X4 965 3.4 GHZ overclocked naar 4.4 GHZ stabiel
    12 GB DDR3 ram
    1x 5850 (ik wil dus nog ene voor crossfire)
    4 HDD's
    Voeding is corsair VX450

    Momenteel is mijn systeem stabiel en trekt mijn voeding het wel hoor maar ik ben aan het twijfelen of dat nog wel het geval zal zijn met nog een 5850 erbij? Wat denken jullie?

    Indien ik toch een nieuwe voeding zal moeten gaan halen dewelke raden jullie mij aan?

    Alvast bedankt.

    Mvg

    Het gaat toch heel nipt worden denk ik hoor want je cpu is flink oc'ed en dat verbruikt toch wel wat stroom.

    Corsair TX650 v2 zal hier perfect tot zijn recht komen.

    met uw huidige voeding zal het idd zeer nipt worden en betwijfel ik of je systeem onder load nog stabiel zal zijn, zeker met die zware overklok.

    je zit voor die 2 5850's in CF aan 302w, kweet nu niet hoeveel je CPU verbruikt maar veel plaats heb je niet meer over.

    Zo te zien heeft die maar 2 x PCIe terwijl 5850 crossfire er 4 nodig heeft? Hoe moet ik dat dan oplossen?

    Gebruik maken van molex adapters.

    Met een voeding van 650W en van een deftig merk kom je toe. Die CPU zal bij volledige belasting wel 125+W trekken, daarmee.

    450W is inderdaad wat nipt, maar een deftige 550W voeding mag geen enkel probleem zijn.

    Na wat opzoek werk heb ik gevonden dat de corsair vx450 eigenlijk een 500w voeding is en met gemak 571.9 w max kan halen.

    This power supply is manufactured by Seasonic. It looks like a Seasonic from SII-12 series (SS-xxxSB) but we couldn’t confirm this. Also Seasonic doesn’t carry any 450 W model, so it seems that this model is manufactured exclusively for Corsair. After opening this power supply we found out that internally it is identical to Antec Earthwatts 500 W, but using better electrolytic capacitors.
    This power supply only uses Japanese electrolytic capacitors from Chemi-Con, with the active PFC capacitor being rated at 105º C instead of 85º C like on other power supplies. This gives us a hint of the quality of this power supply. Antec EarthWatts 500 W, which is basically the same power supply with a different housing, uses Taiwanese caps.
    This power supply uses a single rail design, so there is not much to say here. Antec EarthWatts 500 W, which is basically the same power supply with a different housing, uses a dual-rail design. The difference between the two is only how the OCP (over current protection) circuit is connected. On this power supply this circuit is monitoring all +12 V outputs at the same time, while on the model from Antec this circuit is monitoring two different sets of wires.
    We were really curious to see how much power this unit could really deliver, because by the project used we suspected it could deliver far more than what was labeled – especially because we had already reviewed Antec EarthWatts 500 W, which uses the same design, and it is not only labeled at 500 W but could deliver up to 577 W.

    We tried to see not only the maximum power we could extract from this power supply with it still working inside its specs, but also if all its protections are working correctly. As you know by now, power supplies usually burn when we try pulling more than it is capable of handling if it doesn’t feature overload protection (OLP or OPP; these two acronyms mean the same thing).

    Since we were already pulling from the +12 V output almost the maximum our load tester can deliver to this output – 33 amps – we removed the power supply EPS12V connector from +12V1 input and installed it on the +12V2 input from our load tester. Then starting from pattern number five described in the previous page we started increasing current until the power supply turned off. We figured out that if we pulled more than 44 A (528 W) from +12 V (22 A from the motherboard, video card and peripheral cables and 22 A from EPS12V) the power supply wouldn’t turn on. Phew, we were really cold sweating expecting the worst – that this power supply would explode. But since it shut down, we could testify that overload protection was in action, which is terrific.

    Then we increased current on +5 V and +3.3 V to see if we could pull even more. Under the current configuration if we pulled more than 7 A from these rails the power supply would shut automatically down.

    With this maximum configuration (44 A from +12 V, 7 A from +5 V and 7 A from +3.3 V – i.e., a total of 596 W!) the power supply would turn on and work for around 30 seconds, after that the power supply would shut down due to overload. Isn’t that great to have a power supply with overload protection in action? You can do whatever you want and it doesn’t explode!

    We decreased two amps from the +12 V output and we could make our 450 W power supply to work stable at 570 W at 48º C and with 81% efficiency! Holy cow! You can see the summary for this test in the table below.
    Main Specifications
    Hardware Secrets Golden Award

    Corsair VX450W power supply specs include:


    * Nominal labeled power: 450 W.
    * Measured maximum power: 571.9 W at 47.8º C.
    * Labeled efficiency: Between 80% and 85%.
    * Measured efficiency: Between 84.3% and 88.1% at 115 V.

    Conclusions
    Hardware Secrets Golden Award

    If we could summarize this power supply in just one word it would be “wow!.” Together with Antec EarthWatts 500 W this is the best power supply up to 500 W we have ever seen, bringing the best cost/benefit ratio for the average user building a mainstream PC with a good video card, graduating Summa Cum Laude in our tests. You will bring home a relatively inexpensive power supply that even though is sold as being a 450 W unit can deliver up to 570 W at 48º C – in fact Corsair could have easily labeled this power supply as a 500 W unit, but they preferred to stay on the safe side.
    As we mentioned, this product is identical to Antec EarthWatts 500 W, but using better capacitors – it was really good to see Japanese capacitors on an entry-level product –, a better-looking housing (black vs. standard grey), a better cooling system (120 mm fan vs. 80 mm fan) and more power plugs (six peripheral power plugs vs. three; six SATA power plugs vs. three). But Antec EarthWatts has as a big advantage coming with two video card power cables. In fact this is the only problem with this product from Corsair: if you want to use two video cards in SLI or CrossFire modes you will need to use an adapter to convert a standard peripheral power plug into a 6-pin auxiliary video card power plug. Being in fact a 570 W product, it can easily feed two video cards.

    Dus blijkbaar heeft die wel genoeg power? Ik kan het altijd proberen he, da kan nooit kwaad

    Voedingen lange tijd op hun piekvermogen belasten is dan wel weer slecht voor de levensduur, maar op zich zou die voeding weinig probleem mogen hebben met 2 HD5850's.
