Tagan Dual Engine 800W
Last of the contenders is the Tagan Dual Engine 800W (model TG800-U25). Again, being built as an EPS model, it's bigger than an ATX PSU.
Dimensions are 170(d) x 150(w) x 87(h) mm, so it's 20mm deeper than a standard ATX box - and a mere 1mm higher, too.
The Tagan uses two 80mm fans in a push-pull configuration and, like with the single-fan SilverStone PSUs, these make an unpleasant noise when the power supply is under load.
Unlike the SilverStones, though, the twin-fan arrangement means that the supply stays cool even under heavy loads - as borne out in our testing.
The Tagan held the lowest temperatures. But, since it was the second least-powerful PSU on test, that's not surprising.
All cabling (except power-in, of course) is hard-wired, so there are going to be unused cables that need to be tied and tucked away.
As with the 750W SilverStone, there's no sheathing on Molex or SATA cables. But, unlike any of the other PSUs on test, there is copper-mesh shielding on a variety of other cables - EPS, P4 and PEG (otherwise know as PCIe power).
The PEGs also have RF-chokes - the aim being to stop any electrical interference reaching the graphics cards. However we can't say for sure whether they do make the cards any more stable than they would otherwise be, likewise the rest of the system.
In-pack are mains and Molex-to-twin-floppy-disk cables, plus a bunch of Velcro ties to help keep things tidy. Also provided are some blanking plugs to seal off the unused power leads, along with screws to hold the PSU within the case.
