HuntKey Jumper/R90 300W 80Plus Gold
by Martin Kaffei on March 5, 2011 12:00 AM ESTAppearance and Specifications
Our review sample came without retail packaging, so we'll jump straight to the design and appearance. Above is the R90, with large rectangular cutouts for the rear ventilation. That's a standard HuntKey trait, as opposed to the hexagon/honeycomb ventilation used on many other PSUs. The R90 has a matte black finish, transparent fan blades, and cable sleeving that could easily be mistaken for something from Enermax. It's a decent looking, understated design and the case is only 14cm long.
Given the 80 Plus Gold certification, the use of DC-to-RC VRMs should be too surprising, but it's not something we typically see in the 300W market. Most of the power comes on the two +12V rails and we tested OCP at room temperature. OCP kicked in at 28A, which is definitely more than you'd normally get from a 300W PSU. However, the smaller rails can deliver up to around 100W for peripheral hardware and HDDs/SSDs; that means in typical PCs you'll have less than 28A on the +12V rail to work with (like all DC-to-DC PSUs).
That should still be sufficient for running a moderate midrange or lower GPU. HuntKey informs us that up to a single GeForce GTX 260 or 460 (and maybe even a 560 Ti if your CPU isn't too extreme) should work; on the AMD side, that equates to a single Radeon HD 5850 or 6950 or lower (and you might even manage a 6970 if your CPU isn't too demanding). Then again, erring on the side of caution might not be a bad idea, in which case the HD 6850 and GTS 450 would be a more reasonable limit.
The Jumper 300G has a slightly different appearance. Gone is the matte black exterior, replaced by a shiny silver casing. The cable sleeving is also missing, and the fan grille is different. Internally, the units are the same, but the American market will be getting this rather vanilla looking version.

Kind of stinks that they take away the sleeves, and matte black paint for the American version. I guess shrink tubing isn't to costly... But still.SirGCal - Saturday, March 5, 2011 - link
Especially for the very high cost... It's the little things that start to matter at that price. Wraping and a nice finish is part of those things... Bummer too cause I might have considered it otherwise.Mr Perfect - Monday, March 7, 2011 - link
Yes, don't sell yourself short HuntKey. If you have a quality product, put some quality fit and finish on it. The plain looking case and cables makes the US version look cheap.mindless1 - Saturday, March 12, 2011 - link
It's teenagers or young males who think they are still that feel the need to try to impress others with visual interior effects on a PC, and even among those it is a very small # of the market. Most people's cases have a solid side panel w/o window and not only is it totally irrelevant to them whether it is black painted or sleeved, they couldn't even tell you what color their PSU is or whether it is sleeved.Put the PC out of the way and get some art on the wall if looks are important.

Well, the colour of a PSU does show out the back of a case, and sleeving has a functional effect, not jsuit a decorative one.HangFire - Wednesday, March 16, 2011 - link
A Gold rated power supply is going to appeal to system builders, modders and aficionado's who take pride in their work."Most people" who use "Most people's cases" with a "solid side panel" will be buying the cheapest P/S available, which won't be this one.

Martin,Make it fully modular with a good selection of cable lengths to choose from and I'll pay $100+. Bring on a 200 Watts unit of the same kind and I'll pay the same.

Who knows, maybe they will add another version later. I'm sure HuntKey cares about that. Or other manufacturer will.If HuntKey sells a lot of them other brands will follow. I'm looking forward to this situation since 300W Gold with modular cables is more interesting than 500W+ with Platinum.

to really see how much can run on this 300WATT PSU before it becomes worthless.j-g-faustus - Saturday, March 5, 2011 - link
I expect that I can run a moderately overclocked Sandy Bridge 2600K plus a GPU like GeForce GTS 450 (~100 W DC) and still stay below 80% of the 300 W capacity.This is based on my current 2600K@4.1GHz which draws 145 W from the wall with 8 Prime95 threads. Given 80% PSU efficiency this should be ~116 W DC, plus 100 W for a GPU is just 220 W DC total.
Looking forward to this PSU, hoping that we will see more power supplies with low wattage and high efficiency.
