Thermaltake Toughpower Grand 1200W Power Supply Review




Price Per the Watt:

Power Supply Thermaltake Toughpower Grand at $279.00 = $0.23/Watt (08-2011)


The Thermaltake Toughpower Grand 1200W is a well made unit with good packaging, an excellent set of accessories that includes plenty of well made modular cables and good looks, but how does it perform?

The Thermaltake Toughpower Grand 1200W performance wasn't remarkable - just satisfactory. It produced a decent set of results that passed the ATX12V V2.2 specification, but it wasn't remarkable in any way. DC quality and efficiency are satisfactory with the exception of a dip in efficiency at full load on 110VAC following the OCC power supply testing methodology.

I couldn't recommend this power supply on a cost/performance basis alone, when you can have a Corsair AX1200 for a very similar price. It'll certainly get the job done and is capable of powering any high-end gaming rig with two or even three high-end graphics cards. and on that basis it's certainly deserves an OCC Bronze award - but it's hard to justify $279.00 for this level of performance. For that sort of money you need to be able to award it a Gold, but unfortunately it doesn't quite get there!
