what model is your coolermaster.. if its extremepower, then limit your gfx to a mid range one that requires only 1pci-e 6pin.. eg. 6770 etc.. but it might not be enough for full hd gaming

Hi, can recommend a psu for the following spec? Seems like fsp aurum is the most highly recommended. How about Andyson, OCZ, Enermax or Seasonic PSUs?

i5 2400
Biostar P67b+
Palit gtx460
2x kingston 4gb ddr3 ram
2x sata3 hdd
1x dvd-rw drive
1x pci soundcard

Hi,
got a question regarding electricity consumption.
E.g. a PC with a 500w PSU, running 300w idle and 400w full load.
If this PC is left running idle for 1hr and full load for 2 hrs consecutively, how will the electricity bill be calculated?
(taking SP services rate as 0.2919cents/KWh)

a) [(300/1000)*0.2919]+{2*[(400/1000)*0.2919]}
b) 3*(500/1000)*0.2919

a) but it depends on efficiency also..

75% efficient at 300wDC = 400w AC from wall socket..
75% efficient at 400w = 533w from wall socket

(500w limit is DC, not AC but you are billed using AC draw)

90% eff at 300w DC = 333w AC
90% eff at 400w DC = 444w AC

Total for 75% eff psu = 400/1000*0.2919 + 2*533/1000*0.2919 = $0.428
Total for 90% eff psu = 333/1000*0.2919 + 2*444/1000*0.2919 = $0.356

DIfference = 20% higher bills

Super Flower Golden King 1000W Review
Super Flower is a manufacturer, headquartered in Taiwan but with their factory in mainland China, that's been around making computer chassis and power supplies for quite a long time. Unfortunately, the brand has not been available in the U.S. for some time, although Super Flower units can still be purchased all over Europe and Asia. Here in America, we usually have to wait for a company like Kingwin or Sentey to pick up and re-brand a unit.

The Golden King is the first power supply I've had a chance to review that advertises 80 Plus Platinum efficiency. That means this power supply should be at least 90%, 92% and 89% efficient at 20%, 50% and 100% loads. We will certainly try to confirm this in today's tests.

Kingwin Stryker Fanless 500W Review
Not very long ago, I took a look at a fanless power supply from Superflower that turned out to be the bee's knees when it came to providing stable power at very high efficiency without so much as a cooling fan to help it. At the time, I wished and pined for this unit to come to the North American market, since you cannot buy any Superflower retail units on this continent. Well, Kingwin has granted my wish. They are now offering their own version of this awesome unit which goes by the name Stryker. Let's see if anything has changed about the design.

Without SLI, take 600W gold at least. With SLI, go up to 850W to be comfortable.

Enermax Platimax 1200W Review
Not too long ago, Enermax contacted us with an opportunity to review their new 80 Plus Platinum certified, fully modular power supply, the Platypus... err... sorry.. The Platimax. The Platimax is an upgrade over Enermax's 80 Plus Gold effort, the MaxRevo. Needless to say, we wanted the chance to see if the Platypus.. sorry... Platimax performed at least as well as the MaxRevo, but with better efficiency...
