Cheap TEC PSU!

[Marci]

Becooling (www.aquastealth.com) have a luverly cheap 350w pelt-psu on their site... I just got one and it works out to retail at £54 exc VAT in the UK... not had chance ot wire it up yet, but I can say it is bigger than the swiftech / meanwell one... takes up 2x CD Bays... and requires some soldering skill to attach the pelt to the PSU (you have to solder directly onto a PCB Path) and short the on/off paths... but it's nowt major. If using a pelt you should be capable of doin that neways! And for the gr8 price tag I can put up with it...!

"This power supply will provide 12 volts with 24 amps to the peltier"
You want at least 14v for maximum benifit of a 15v TEC. So this is not optimal. Thats a nice clock out of that stepping especially at that voltage, Marci. :D You got a 3dmarkscore for that?

Got the chip up to 2.5Ghz, but 3DMark score comes out low at the mo...

Here's the one at 2.4Ghz - http://service.futuremark.com/compare?2k1=5624296

I know you need 14/15v optimal, but most conveniently sized internally mountable PSUs only give out 12v... including the siwftech/meanwell offering which this is intended as a competitor for... Icee, Opp and all the other guys on here use 12v PSUs for their TECs. A TEC running at 12v is still better than no TEC at all....

My highest score however is this one:

I forgot to ask with what cooling did you get your chip to that speed and at what voltage? I have had my chip @ 2400Mhz but was unstable while I was using 1.925v - short of the 2.2v I have available; my cooling wasn't an issue. I have yet to see how far my fsb can climb past 200Mhz with stock Vdd.

Thats a nice score for the PIV rig. Only 2000+ and your be at the top of the orb.:banana:

I generally always stick at 200FSB, so 2400 was 200x12, 1.825v (I think), 3v to Mem, Cas2-2-5-2-1T-8-2-640ps. 2500 was at 200x12.5, 1.925v.

Cooling on CPU - Swiftech MCW462U, 1048 Pump submerged in 15litre tank, D-Tek heatercore and 1x120mm Panaflo shrouded one side, mounted externally.

Cooling on GPU - Swiftech MCW40, 1046 Pump submerged in same tank, Maxxpert 1x120mm MonoRad.

All mine were done at stock VDD.

The PIV rig is creeping back into action in MajorMav's prometeia as we need to do a review for Corsair on the PIV board, as well as on the NForce2, so ya never know... we may better those scores yet! And to add to the equation, Majormav just got a much better clocking Rad9700 Pro from me that does more on mem than previous card...
