HP t620 Plus: Hardware 


 


 

 



t620 Plus

I don't have a t620 Plus. Scott (scottie4442) does and has kindly provided the photos and the additional information on this page.

Obviously the motherboard is the same as the ordinary t620, however it does come fitted with a more powerful Quad core CPU than the Quad core option of the standard t620. In this tab I just highlight the differences from the t620.

Appearance

HP t620 Plus Thin Client
The HP t620 Plus is the fatter version of the t620. The wider chassis accommodates an expansion card. The front panel is just wider whilst the rear panel carries an additional serial port, parallel port and the back panel of any expansion card you have fitted.

There is a factory-fit option of an additional graphics card - an AMD FirePro 2270 Multi-View Professional Graphics dual-head graphics card - but in this case Scott has chosen to install a four-port gigabit PCIe NIC in the expansion slot.

Specifications

Other than the added serial port and parallel port the t620 Plus is fitted with a more powerful AMD Quad-Core GX-420CA 64-bit SOC (2.0 GHz, 2 MB L2 Cache) with AMD Radeon HD 8400E (600MHz GPU) Graphics.

There is also the Riser Card/Expansion Slot which the specification sheet describes as "PCIe 2nd Gen, x16 slot with x4 channels". By this they mean that the connector is physically x16 size, but electrically it only supports x4.

Obviously the power consumption will be higher with the different processor - the TDP of the GX-420A is 25W compared with 15W for either of the CPUs fitted in the standard t620. You also have to add in the power consumption what ever you choose to fit in the PCIe slot. HP recognise this by supplying the t620 Plus with an 85W PSU rather than the 65W PSU that comes with the standard version.

Additional photos

HP t620 Plus Thin Client fan
On removing the side cover the first thing you see is a large fan - not the usual thing you find fitted to a thin client. HP obviously are catering for those users who are fitting high-power expansion cards.

The fan plugs into a connector adjacent to one of the internal USB ports (the one by the CMOS push button). I guess you can unplug it if you don't need it, but Scott does report it as being "..super quiet and barely noticeable..."

HP t620 Plus Thin Client expansion card fitted
With the fan out of the way you can see how the expansion card sits within the chassis. It's plugged into the riser that fits into the socket on the edge of the motherboard just by the RAM. (See below).

HP t620 Plus Thin Client Riser
This is the riser that plugs into the expansion slot and provides the PCIe socket for the expansion card. There's also additional metalwork behind to ensure it is securely braced within the chassis.
