460 Watts Nätdel till MSI GTX780 Gaming ??

Det är på gränsen, det beror också på vad för klassificering det är på nätdelen. Som du ser på bilden så är nätdelen mindre effektiv vid högre loads, så den kanske inte pallar alls vid tungt arbete.

Codegen 460 Watt

You'll note that there's no 80 Plus certification on this one, which isn't too surprising considering the target market.

It's clear that some PSUs should never see retail shelves in Europe. The Codegen P-Case 460W belongs in this classification if you want a 460W PSU. In fact, the Codegen is a ~230 watts power supply without power factor correction--not to mention the fact that the efficiency is always below 74%. If you just need a cheap power supply that will function at loads under 250W, perhaps budget products will fit the bill, but we'd suggest looking elsewhere as long-term power costs (and the risk of damaged components) makes this a gamble at best. In our case, the PSU died at 50% load.

In summary, the Codegen P-Case 460 from Q3335-A2 bundle is one of the worst PSUs we have seen so far. It doesn't have any special features beyond an acceptable noise level (at low load). We can hardly recommend a 460W PSU with 230W real power and no power factor correction. In addition the PSU died during our test. The whole bundle costs about 30 EUR in Europe.
